Intelligent venous blood collection robot as a fully automated surgical equipment, can automatically complete the disinfection, puncture operation, can replace the health care workers in contact with the patient, while equipped with its own disinfection system, so as to maximize the avoidance of cross-infection; the robot has a stronger than human imaging ability, recognition ability, operational stability and the efficiency of the implementation of processed work, to solve the problem of low success rate of venous puncture, In addition, the current automatic blood classification technology and automatic drug sorting technology has been very mature, but blood sample collection and drug injection still need to be completed manually by nurses, venipuncture robot through the hospital blood collection and injection automation of the ? The last kilometer?
The intelligent venipuncture blood collection robot uses near-infrared light and ultrasound dual-modality imaging to identify blood vessels at different scales, and its depth of field of vision and accuracy is stronger than the naked eye, allowing it to accurately identify blood vessels in obese patients as well as dark-skinned patients, and with the help of intelligent algorithms, the robot can dynamically track the changes in the position of puncture needles and blood vessels. In addition, the robot adopts high-precision servo motors to control the puncture action, and utilizes sensors for real-time feedback, so the accuracy and stability of the action exceeds that of human operation.
In China, 78% of nursing work is related to intravenous infusion therapy, and more than 90% of hospitalized patients receive intravenous infusion therapy. The difficulty of vascular puncture, the complexity of the patient's underlying condition, encountering obese patients, the elderly, shock patients and other common conditions, it is difficult to carry out puncture successfully under direct vision. Multiple punctures can easily lead to phlebitis and other complications, affecting clinical treatment. At the same time, healthcare workers are constantly faced with occupational exposure during the puncture process, and the ongoing new coronary outbreak has greatly increased the risk of viral transmission during routine diagnostic and therapeutic operations, including vascular puncture, jeopardizing the health of medical personnel and the community at large.
The robot has three main components: a near-infrared imaging camera that accurately identifies and restores delicate veins hidden under the skin. An ultrasound probe that accurately detects the depth and thickness of veins inside the body. The small, dexterous robotic system automates the process of puncturing and collecting blood by delivering the tip of the needle into the thin vein with pinpoint precision.
Under near-infrared light, the veins of even obese people and those with dark skin are clearly visible; then again, the veins of the elderly and children, even though their veins are relatively small and difficult to observe, are clearly captured by the camera. In addition, the veins themselves have a complex structure, and may bifurcate into multiple veins, or transition and taper into capillaries, which makes lancing quite difficult as well, but by simply utilizing near-infrared imaging, the distribution of the blood vessels can be easily identified, and spatial information about the veins in the patient's injection area can be obtained .
This robot brings a boon to nurses.
